Specifies values used by the IDirect3DRMMesh::GetGroupMapping and IDirect3DRMMesh::SetGroupMapping methods to define how textures are mapped to a group.
Type equivalent to D3DRMMAPPING.
Texture wraps in the u direction.
Texture wraps in the v direction.
Texture wrapping is perspective-corrected.
The D3DRMMAP_WRAPU and D3DRMMAP_WRAPV flags determine how the rasterizer interprets texture coordinates. The rasterizer always interpolates the shortest distance between texture coordinates; that is, a line. The path taken by this line, and the valid values for the u- and v-coordinates, varies with the use of the wrapping flags. If either or both flags is set, the line can wrap around the texture edge in the u or v direction, as if the texture had a cylindrical or toroidal topology. For more information, see Direct3DRMWrap.
